Extreme summer heat thins out diesel fuel, making it harder for low-quality or worn fuel injectors to maintain correct rail pressure.

Genuine Bosch common rail injectors are engineered with precise tolerances to ensure consistent fuel atomization, preventing hard starts, rough idling, and lost fuel economy.
